Interesting, here's the actual product specs: https://www.tachyum.com/assets/img/Datasheet-216.pdf

While I can imagine niche applications I cannot see this becoming mainstream soon. Usually software needs to be rewritten to take advantage of the FPGAs - often using different algorithms.

Looks very similar to what Transmeta did. Hard to know if there are any real gains without hands on the actual hardware. 4 instructions per clock as 2.8GHz is not exactly earth shattering performance by modern standards.

No mention of process node or TDP...

The architecture looks fairly different than Transmeta's architecture to me although the purported multiple ISA user feature is similar.

They presented some high level stuff at ISC 2020. https://www.tachyum.com/assets/img/Tachyum_20ISC20.pdf

The image on slide 7 looks almost exactly like this design (including the 8x8 core matrix)

Which targeted the same market. The problem is, this is actually a pretty hard architecture to program for.
